A blog by Geert van der Cruijsen on Apps, Cloud & ALM

Tag: iOS

For a while now (september 2015) Apple requires apps that are submitted to iTunes to be 64 bit. When building your app for the simulator this isn’t required because app doesn’t go through the Apple screening. Since iOS 10.1 update however Apple added a little popup that checks if an app supports X64 and otherwise will show you a popup telling: “[App name] may slow down your iPhone”. It will only show the error message once and is meant for old apps which are added to the store before september 2015 and are still on peoples phones/tablets who need to update to X64.

Popup message: [App name] may slow down your iPhone

The fix is quite easy. just set the iOS build to support X64 also when building for the simulator.

Visual Studio

Although this is a small issue i got some questions by new developers what this message meant. so hopefully this blogposts helps those who were questioning why this message is showing up all of a sudden.

Happy coding!
